The lines of evidence are multitudinous and in order to find some of the answers you will need to study long and hard at length and in depth, as so many have done since before Darwin. Take a university degree course and be enlightened. http://en.wikipedia.org/wiki/Evidence_of_common_descent

What ancestor is the one that has given rise to two or more lines of descent?
A common ancestor is on that has given rise to two or more lines of descent.
Do you believe that this evidence gives support to the theory of evolution?
I do not so much " believe it " as I an convinced by the myriad lines of converging evidences that support the theory of evolution by natural selection. talkorigins.org
Is evolutionary true?
Yes, the theory of evolution is widely accepted as a scientific fact. It explains the diversity of living organisms on Earth through the process of natural selection, genetic variation, and adaptation over time. Multiple lines of evidence from various scientific fields support the theory of evolution.
When did the human and chimpanzee lines separate?
Science believes that the Human-Chimp common ancestor lived around 7 million years ago.
What are the differences between Darwin's theory of evolution and conflicting theories?
It is no longer Darwin's theory, as Darwin has been dead about 130 years. There are no credible alternatives to the modern theory of evolution by natural selection. So, the differences is; the theory of evolution by natural selection is supported by myriad lines of converging evidence and explains the natural phenomenon that is evolution very well. The " conflicting theories " have no evidence supporting them and explain nothing.
What are the four lines of evidence supporting evolution?
Genetic studies, including comparative genomics. Morphological assays in comparative morphology. Developmental studies in embryology. Palaeontology, which includes studies of the morphology of extinct species. Note that one could just as easily identify ten distinct lines of evidence, or a hundred, depending on how one classifies these lines.
Why do evolutionist believe in human evolution?
Answer 1Evolutionary biologists do not need to " believe in " anything as the evidence for human evolution us overwhelming and comes from myriad converging lines. One only has to put aside whatever ideological blocking one has and accept the evidence here.Google, ' human evolution ' and see that we are a great ape amid the larger family of great apes.Answer 2One can quibble about the best word to describe acceptance of evolutionary theory. I, for one, think that believe is an acceptable word. I believe that evolutionary theory is correct, at least in its fundamental principles of common descent and natural selection. I believe so because of the same reasons most scientists and everybody else familiar with scientific principles, findings in palaeontology and Biology believe so: because of the evidence. The evidence for common descent and natural selection stems from many independent lines of research in biology and palaeontology. Check links below for more information.
Describe three lines of evidence that support the theory of evolution Provide an example for each line of evidence you list?
Fossil Record the ordered array in which fossils appear within layers of sedimentary rocks. Comparative Anatomy comparison of body structures in different species, which give signs of common descent. Biogeography the geographical distribution of species.
Why is darwin's idea of evolution considered a theory?
Because it is an internally consistent explanation of a mechanism of evolution that is supported by many lines of converging evidence, that has been repeatedly tested and is capable of making testable predictions. Pretty much the scientific definition of theory.
What does it mean when it states that evolution is just a theory?
Evolution is a fact. The theory of evolution by natural selection is what you are trying to talk about. When someone says " evolution is just a theory " they are using the vulgar, common sense of the word theory. They mean guess, hunch and the like. The theory of evolution by natural selection is in the scientific sense of the word theory, which means a body of explanatory work supported by myriad lines of converging evidence that has been tested rigouusly and replicated often. Any good dictionary uses this scientific meaning of theory as the primary meaning of the word.
What do you think of the theory of evolution?
It does not mater what anyone thinks about the theory of evolution by natural selection. The theory of evolution by natural selection is the best explanation we have for much of the observed and observable fact of evolution. The theory is internally consistent with the fact of evolution, it is supported by myriad lines of converging evidence and it generates testable predictions in the form of scientific hypothesis. The opinion of no one is needed by the theory of evolution by natural selection and educated people have come to accept the theory.
What do evolutionists and creationists both agree on?
Not much. While they both accept that life is here, they are two totally different ideas on how we got here. Evolution says that all life forms gradually developed from a common ancestor over millions of years. Creation says that everything was spontaneously created as they are by the God of the Bible within six days only a few thousand years ago.
